For his part, Charles has been trying his best not to let his jealousy become irrational. James is just a friend, to the both of them, and if Erik wants to spend time with him then that's no different from him wanting to spend time with Alex, or Sean.

Only Charles can't quite make himself believe that. It's something in the way James is, the way he behaves around Erik. Charles doesn't need to be a telepath to see the attraction there, though Erik seems oblivious.

The final straw is when Charles watches them ride off together on Erik's bike. That bike had been a gift from him, and he'd never intended Erik to share it so readily. It hurts him in a way he can't describe.
